99
100 ~1. Register LPS8v2 gateway to TTN so provide a LoRaWAN coverage. See section “[[Gateway Registration for Semtech UDP ~~-~~-~> Primary LoRaWAN Server>>url:http://wiki.dragino.com/xwiki/bin/view/Main/Notes%20for%20TTN/#H2.A0GatewayRegistrationforSemtechUDP]]” 
101
102 2. Register LA66 Shield to TTN and uplink Temperature to TTN. See section “[[Example: Log Temperature Sensor(DHT11) and send data to TTN, show it in Node-RED>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20LoRaWAN%20Shield%20User%20Manual/#H1.7A0Example:LogTemperatureSensor28DHT1129andsenddatatoTTN2CshowitinNode-RED.]].”

121
122 This example is almost the same as Example1, the difference is that this example use the built-in LoRaWAN server (TTNv3 Stack) in LPS8v2. While Example 1 use the public TTN server.
123
124 TTN v3 stack has the same configure method as the public TTN server. When user test example 2 here. User need to log in the TTNv3 stack in LPS8v2 as per below:
